Hello!
I still have this issue with my e1000: it works slower than expected,
even with small ping packets:
- n400c notebook with e100 and
- lenovo t60 with e1000 are connected to a 100mbit/s soho switch
- both hosts ping 62.65.138.66 (a host near to me in the internet)
- both hosts route through 62.65.138.65 (a soekris net5501)
- both hosts are idle, running x11
ping results:
to 62.65.155.65:
n400c: 0.2 to 0.3 ms
t60: 7 - 8 ms
to 62.65.138.66:
n400c: 7 - 10ms
t60: 150 - 650ms, some peaks to 15-80 ms only
Has someone an idea, what could be wrong?
CC on reply, please.
Sincerly,
Nico
